The Caleffi DISCAL micro-bubble coalescing air separator with high discharge capacity and unique chamber design, automatically and efficiently rids system gasses. A very robust design and 100% anti-corrosion components enable DISCAL to provide a long, trouble free life. The DISCAL air separator is used to continuously remove the air contained in hydronic circuits of heating and cooling systems. The air discharge capacity is very high. They automatically remove all the air present in the system down to micro-bubble level with low head loss due to the special internal shape of the separator body. Flow direction of the DISCAL air separator is bidirectional; flow in either direction is permitted.The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from noise, corrosion, localized or mechanical damage.

The valves can be used in a wide variety of heating and condensing cooling applications, primarily designed for use with baseboard, fan coils, radiators, convectors, air handlers, heat pumps and radiant applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 93% less energy usage\u003c\/li\u003e\n\u003cli\u003eUniversal Installation Orientation\u003c\/li\u003e\n\u003cli\u003eUsable on Condensing Chilled Water Installations\u003c\/li\u003e\n\u003cli\u003e12 valves on one 40VA transformer\u003c\/li\u003e\n\u003cli\u003eMulti-Function LED\u003c\/li\u003e\n\u003cli\u003eQuick Connect Wiring\u003c\/li\u003e\n\u003cli\u003ePush button actuator replacement\u003c\/li\u003e\n\u003cli\u003eEasy wire quick connections Manual override button\u003c\/li\u003e\n\u003cli\u003ePositional indicator\u003c\/li\u003e\n\u003cli\u003eMax Operating Pressure: 300 PSI\u003c\/li\u003e\n\u003cli\u003eMax Shutoff Pressure: 125 PSI\u003c\/li\u003e\n\u003cli\u003eMax Ambient Temp.: 135 degrees F\u003c\/li\u003e\n\u003cli\u003eFluid Temp.
